.SH DESCRIPTION
.sp
.LP
The \fBfp\fR port driver plug-in \fB/usr/lib/cfgadm/fp.so.1\fR provides the
functionality for Fibre Channel Fabric device node management through
\fBcfgadm\fR(8). \fBcfgadm\fR operates on attachment points. Attachment points
are locations in the system where hardware resources can be dynamically
reconfigured. Refer to \fBcfgadm\fR(8) for additional details on attachment
points.
.sp
.LP
For Fibre Channel Fabric device node management, each \fBfp\fR port node is
represented by an attachment point in the device tree. In addition, each Fibre
Channel device is represented by a dynamic attachment point. Attachment points
are named through \fBap_ids\fR. Two types of \fBap_ids\fR are defined: logical
and physical. The physical \fBap_id\fR is based on the physical pathname. The
logical \fBap_id\fR is a shorter, more user-friendly name. For \fBfp\fR port
nodes, the logical \fBap_id\fR is the corresponding disk controller number. For
example, \fBc0\fR is a typical logical \fBap_id\fR.
.sp
.LP
Fibre Channel devices are named with a port World Wide Name (WWN). If a disk
device is connected to controller \fBc0\fR, its \fBap_id\fR can be:
.sp
.in +2
.nf
c0::50020f2300006077
.fi
.in -2
.sp

.sp
.LP
where \fB50020f2300006077\fR identifies the port WWN of a specific Fibre
Channel device.
.sp
.LP
Each device on the Fibre Channel private loop port, Fabric port or public loop
port is probed and made available to Solaris by default. Devices connected to
the Fibre Channel Fabric port or public loop port can be made unavailable to
Solaris by initiating an application or an end user operation. The operation is
similar to the hot unplugging of devices by way of management user interfaces.
Applications or users can use the \fB/usr/lib/cfgadm/fp.so.1\fR library to
enable \fBlibcfgadm\fR to provide interfaces to accomplish this task.
.sp
.LP
The list of currently connected Fabric devices is generated in the form of the
attachment point.
.sp
.LP
A simple listing of attachment points in the system includes attachment points
at \fBfp\fR port nodes but not Fibre Channel devices. The following example
uses the \fB-a\fR flag to the list option (\fB-l\fR) to list Fibre Channel
devices:

In this example, the \fBfc-fabric\fR type of \fBap_id\fR \fBc0\fR indicates
that the \fBfp\fR port is connected to Fabric. For an \fBfp\fR port with a
Fabric-related type such as \fBfc-fabric\fR and \fBfc-public\fR, device node
creation happens by default at the boot time and can be managed by the
\fBcfgadm\fR configure and unconfigure operations. The  \fBfc-private\fR  type
of \fBap_id c1\fR indicates that \fBfp\fR port is connected to private-loop and
device node creation happens by default as well. The \fBfc-pt_to_pt\fR type of
\fBap_id c2\fR indicates that the \fBfp\fR port is directly connected to
another \fBN_port\fR and device node creation also happens by default. The
\fBfc\fR type of \fBap_id c3\fR indicates that nothing is attached to \fBfp\fR
port \fBc2\fR. The Type field of a Fibre Channel  device \fBap_id\fR shows the
SCSI device type of LUN 0 in the device.
.sp
.LP
A Fibre Channel device with multiple FCP SCSI LUNs is configured into Solaris
and each \fBFCP SCSI LUN\fR is available as a Solaris device. Suppose that
ap_ids \fBc0::50020f2300006077\fR and \fBc0::50020f23000063a9\fR represent
Fibre Channel devices with multiple \fBFCP SCSI LUN\fRs.

In this example, the \fBap_id c0::50020f2300006077,0\fR identifies the \fBFCP
SCSI LUN 0\fR of the Fibre Channel device which is represented by port \fBWWN
50020f2300006077\fR. The Fibre Channel device is reported to have 4 \fBFCP SCSI
LUN\fRs and they are all configured. \fB4 FCP SCSI LUN\fR level ap_ids
associated with port \fBWWN 50020f2300006077\fR are listed. The listing also
displays \fBFCP SCSI LUN\fRs for unconfigured Fibre Channel devices. The Fibre
Channel device represented by \fBc0::50020f2300005f24\fR is reported to have
two \fBFCP SCSI LUN\fRs. The configure operation \fBon c0::50020f2300005f24\fR
creates two Solaris devices. The \fBType\fR field of \fBFCP\fR \fBSCSI\fR
\fBLUN\fR level ap_ids show the \fBSCSI\fR device type of each \fBLUN\fR. When
a Fibre Channel device has different device type \fBLUN\fRs, the \fBType\fR
field reflects that.

supported:
.sp
.ne 2

\fB\fBconfigure\fR\fR
.ad
.sp .6
.RS 4n
Configure a connected Fibre Channel Fabric device to a host. When a Fibre
Channel device is listed as an unknown type in the output of the list operation
the device might not be configurable. No attempt is made to configure devices
with unknown types. The force option (\fB-f\fR) can be used to force the
\fBfp\fR port driver plug-in to make an attempt to configure any devices. Any
errors in the process are reported. By default, each FCP SCSI LUN that is
discovered on a Fibre channel Fabric device is configured. However, FCP SCSI
LUNs that are specified in the "pwwn-lun-blacklist" property in the
\fBfp.conf\fR file will remain unconfigured. The FCP SCSI LUN level listing
reflects the state of such FCP SCSI LUNs. They stay in the "unconfigured" state
after reboot or Solaris Dynamic Reconfiguration on the controller that they are
connected through. Refer to \fBfp\fR(4D) for additional details on the
"pwwn-lun-blacklist" property.

.ad
.sp .6
.RS 4n
Unconfigure a Fibre Channel Fabric device from a host. This device stays
unconfigured until the next reboot or Solaris Dynamic Reconfiguration on the
controller that the device is connected, at which time all fabric devices are
automatically enumerated. The default behavior may be changed through the use
of the "manual_configuration_only" property in the \fBfp.conf\fR file. If the
property is set, the device remains unconfigured after reboot. Refer to
\fBfp\fR(4D) for additional details on the "manual_configuration_only"
property.
.RE

For Fibre Channel private loop devices and \fBN_Port\fR point-to-point devices,
the \fBconfigure\fR command returns success without doing any operation. The
\fBunconfigure\fR command is not supported on the private loop devices and
\fBN_Port\fR point-to-point devices. The private loop  devices and \fBN_Port\fR
point-to-point devices are configured by Solaris Fibre Channel drivers by
default and are not managed through end user- or application-initiated
operations. The \fBpwwn-lun-blacklist\fR  property in the \fBfp.conf\fR  file
is applied to the private loop device and \fBN_Port\fR point-to-point device in
the same way it is applied to a Fabric device.

.RE

All Fibre Channel devices are available to Solaris by default. Enabling only a
subset of Fabric devices available to Solaris by default can be accomplished by
setting the property "manual_configuration_only" in \fB/kernel/drv/fp.conf\fR
file. When "manual_configuration_only" in \fBfp.conf\fR is set, all Fabric
devices are not available to Solaris unless an application or an end user had
previously requested the device be configured into Solaris. The \fBconfigure\fR
state-change command makes the device available to Solaris. After a successful
\fBconfigure\fR operation on a Fabric device, the associated links are added to
the \fB/dev\fR namespace. The \fBunconfigure\fR state-change command makes a
device unavailable to Solaris.
.sp
When a Fibre Channel Fabric device is configured successfully to a host using
the \fB-c\fR \fBconfigure\fR operation, its physical \fBap_id\fR is stored in a
repository. When a Fibre Channel Fabric device is unconfigured using the

the same repository. All fabric devices are automatically enumerated by default
and the repository is used only if the \fBfp.conf\fR
"manual_configuration_only" property is set. Refer to \fBfp\fR(4D) for
additional details on the "manual_configuration_only" property.

.sp
.LP
Do not use hardware-specific options for the repository update under normal
\fBconfigure\fR/\fBunconfigure\fR operations. The hardware-specific options are
expected to be used when the node creation of a Fabric device fails at boot
time and the error condition is considered to be permanent. The
\fBunconfigure\fR command with \fBforce_update\fR hardware-specific option
unconditionally removes the attachment point of a failing Fabric device from
the repository.
.SH NOTES
.sp
.LP
For devices with unknown or no SCSI device type (for example, a Fibre Channel
Host Bus Adapter), the \fBconfigure\fR operation might not be applicable.
.sp
.LP
The \fBconfigure\fR and \fBunconfigure\fR commands operate on the Fibre Channel
device level which is represented by port WWN ap_id. If a Fibre Channel device
has multiple FCP SCSI LUNs configured, the \fBconfigure\fR command on the
associated port WWN ap_id results in creating a Solaris device for each \fBFCP
SCSI LUN\fR unless it is specified in the "pwwn-lun-blacklist" property in the
\fBfp.conf\fR file. The \fBunconfigure\fR command removes all Solaris devices
associated with the port WWN ap_id. The \fBFCP SCSI LUN\fR level ap_id is not
valid for the \fBconfigure\fR and \fBunconfigure\fR commands.
.sp
.LP
The deprecated \fBshow_FCP_dev\fR option has been replaced by the new
\fBshow_SCSI_LUN\fR option, and the deprecated \fBunusable_FCP_dev\fR option
has been replaced by the new \fBunusable_SCSI_LUN\fR option.
